THOMAS PROSSER, OF MONTREAL, QUEBEC, IAXADA, ASSIGNOR OF ONE- I'IALF TO JOHN DUMl-XRESQ, OF SAME PLACE.

APPARATUS FOR OPERATING SELF-FLUSHING CLOSETS.

SPECIFICATION forming part of Letters Patent No, 279,183, dated June 12,1883

I Application tiled October 21, 1852. (No model.)

To all whom it may concern:

Be it known that I, THOMAS Pnossnn, ot the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Apparatus for Operating Self-Flushing (Jlos ets; and Ido hereby declare that the ibllowing is a full, clear, and exact description ot' the same.

My invention is specially intended for use in hotels, railway stations, and other places where closets are in public use, as not only is the working automatic and certain, but the apparatus cannot be tampered with, and no waste of water can occur. i

The principal feature of the invention is that the cistern or vessel for holding water in the apparatus is normally drythat is, always its other end a link, to the end of which is socured the washer or stopper of the outlet, this link being slotted to receive the rod of the ballcock,"whereby the inlet is held closed when the stopper is lifted, and opened when the outlet is closed.

For full comprehension of the invention reference must be had to the annexed drawings, in which- Figure 1 is a longitudinal sectional elevation of the apparatus with the parts in, their usual position; and Fig. 2, the same, but showing the position of the parts at the instant when, by pressure 011 the seat, the outlet is closed an d inlet opened and the cistern begins to fill.

Similar letters ot' reference indicate like parts. i

A is the cistern, made of east-iron, galvanized iron, wood lined with lead or zinc, &c., or any usual or suitable material, and preferably of such size as to contain up to the line of fiot-ation of the ball the quantity sufficient to flush the basin-say about two gallons. The cistern is covered with a lid, A.

B is the inlet-pipe to the cistern, connected with the main, and B the outlet-pipe, taken from the cistern to the arm of the basin,which is preierably ahopper-basin and trap.

(,i is a Lambert ball-valve, 0 being the rod, and C" the ball stopping and regulating the admission of water to the cistern. This ball (7 is raised and lowered, irrespective of its flotation, by means of a slotted link, D, through which the rod 0 passes, this link being pivoted to the end ot' the lever E, fulcrumed in suitable bearings, c, formed on the lid A.

011 the lower end of the linkD is carried the washer or stopper F,whieh maybe made either as shown or of any form found suitablefor clos ing the outlet B.

-The outer end of the lever E is connected by means of a rod or link, G, with the seat H, resting on gndgeons 71 in proper bearings, the relative position of E and H being adjusted by jam-nuts working on the screwed end of rod G;

On the front end of the lever E is secured a weight, E, sul'iicient to counterbalance the weight of the ball and stopper F, keeping the inlet B closed and the outlet B open, this being the normal position of the apparatus.

The operation of the invention as follows: \Vhen pressure is brought to bear upon the seat sufficient to overcome the resistance of the weight E, the front end ot' the lever E is raised by the rod G, the rear end being correspondingly depressed, thus allowing the ball 0 to fall, thereby opening the inlet-pipe B, and simultaneously closing, by means of the washer F, the outlet-pipe B. The water then flows into the cistern until the'ball Ois raisedtherewith to such aheight as to close the inlet-valve 'l'reezing of its contents is entirely done away with.

'\Vhat I claim is as follows:

1. In an apparatus for operating self-flush ing closets, the combination of a cistern or reservoir, normally dry, with inlet and outlet valves controlled by a pivoted weighted lever fuleruined in bearings above the water-level of the cistern, and connected by a rod with the rear of the seat, the whole operated automatically by pressure on such seat, all. as herein set forth, and for the purposes described.

2. The combination, with the normally-dry cistern A, of a pivoted weighted lever connected by a rod with the rear of the seat and operated by pressure thereon, and a slotted link pivoted to the lever and carrying a stopper for the outlet, and serving to raise a balleoek for regulating the supply, whereby the inlet is held closed when the stopper is lifted, and the inlet shall be opened when the outlet is closed, and the exact quantity of water to be discharged automatically gaged, all as herein set forth.
